SAFETY CAR-NET.

T whom it may concern. 4 Be it known that LHAnnisoN C. MAT- 'rHEws, a citizen of the United States, residing at Abbott, in the county of Hill and State of Texas, have invented certain new and useful Improvements in Safety Car- 'Nets, and I do hereby declare thejfollowa safety deviceadapted to be attached to freight cars, the same closing the space between ad acent cars to prevent the passage of a person tothe wheels of a car should he fall or be thrown from the roof of a car.

A further object of this invention is to provide a guard, which will automatically adjust itself to the distance between) the cars when the train is rounding a curve so that the space between the cars will be normally closed to the trainman.

. A still further object of this'invention is to provide a safety net of this character,

which will be simple, practical and comparatively inexpensive in construction, and one that can be manufactured and sold at a low cost.

With these and other objects in view, the invention consists in the novel combination and arrangement of parts hereinafter more fully described and set forthin the claims hereto appended.

Application filed. May 31, 191.7. Serial No. 171,985;

Like numerals of reference designate corresponding parts in all the figures of the drawings. 7

Referring to the drawin s, the numeral 1 freight car of any ordinary construction and to which my improved safety net is adapted to be applied.

' My improved safety net comprises in its construction, the rectangular "attaching or,

supporting plates 2-, which are secured to theends of the car at a spaced distance apart intermediatethe' ends thereof by suitsuitable fastening means. A cylindrical member 4 is formed 1 integrally with one face of the plates 2 and horizontally therefrom, and is adapted to have located therein, a coiled spring5. The outer open ends of the members 4 have bushings 6 fitted therein.

A flexible netting 7 is constructed woven material and secured by its side edges between the, opposing faces of the cylin drical members 4 when the same is secured to one end of a carat a spaced distance apart, thus closing the space between the end of the cars and the outer ends of the cylindrical members l, as shown in Fig. 2.

, guard rail 8 rectangular in cross sectlon constructed of suitable metal has se of any l cured to one face adjacent each end, the

horizontally extending plunger rods 9, which rods 9 are adapted to be slidably arranged in the tubular or cylindrical members 4E, and the rods have secured adjacent their inner ends, pins 10, which are adapted to abut the. outer ends of the springs 5, so as to permit the] springs to be moved inwardly when pressure is applied to the front face of the rail 8, thereby compensating for and permitting the bar to assume different angular positions, so that the guard is rendered automatically adjustable to accommodate itself to the changes with relation to the adjoining ends of the cars when the cars are traveling upon straight and curved portions of the track, during which the adjusting motion of the plungers may move to different distances within the cylindrical members 4. The springs take up and absorb all shocks and jars, which may be sustained by theguard rails 8 and also normally urge the plunger rods outwardly in an extended position permitted by the distance between the ends of the cars so as to always close the intervening space or'gap forthe prevention of accidents of the character described.

Supporting rings ll'are slidably arranged upon each of the rods 9,,and1have. secured thereto,a suitable netting of woven material, designated 12. The side edges-of the netting 12 are secured to the rings 11 so that when. the :rods -9 are moved inwardly against the tension of they springs, the netting 12 may collapse and be readily extended zwhen thespringst urg therods outwardly in th 1 extended positions again.

It is to be understood that the nettings are to be secured to each end of the car to.

close the gap between the sameand, the adjacent car. It is alsoto be, understood that the device is so secured to the ends of the cars as not to interfere with the operationriof the brakesvjthereof or with, the proper handling of the car;

;,What isclaimed is: l

t 1, In a safety attachment for cars,the combination with a car, plates secured to the car, cylindrical members carried by ,the

plates, sprlngs located in the cylindrical 5 members, a guard rail, plunger rods carried by the guardrail and movablein the cylindrical members, springs located, in the cylindrical members and surroundlng. the

plunger rods of the guard r ail,= and ;a net-' ting material secured to the cylindrical members and plunger rods, as. and for the purpose specified. 1 I

2..In a safety attachment for cars, the

combination Wllll'l a car body, attaching plates secured to the ends of the body at a spaced distance apart, cylindrical members formed integrally with and extending at right angles from. the plates, coiled springs located inthe cylindrical members, a guard rail, plunger rods secured to'and; extendingfat'mght' angles from the uard, rail adjacent each end thereof, said plunger rods slidably arrangedv in the cylindrical mem bers and bearing against the springs, a foraminous material secured to the opposing faces of the cylindrical members, rings, slidably arranged on the rods, and a foraminous copies of this patent may be obtained for material secured:to the rings, as and for the purpose specified;

8. In a safety attachment for cars, the

'combinationiwithgia car body, rectangular attaching plates secured to the ends of the carata spaced distance apart, cylindrical members formed integrally with and extending at right angles from one-face of the plates, springs located in the cylindrical members, 7

cured to and extending at right angles from one face of the guard rail adjacent each end thereof, said plunger ro ds slidably arranged in the cylindrical members and bearing a guard rail, plunger rods seagainst the springs, saidisprings normally urging the guard crails outwardly to compensate'v for the intervening. space between the, adjacent car ends, and a' foraminous body. secured between the opposing faces ger rods. 7

4. In ,a safety attachment for cars, the combination with'a b ox car, of a pair of rectangular attaching plates secured to the ends Of the, box car at" a spaced distance apart, cylindrical members secured to and ext ndlngat right angles from one face of the attaching plates, coiled springs arranged in the cylindrical members, a foraminous ,body secured by its ends to the opposing faces of the cylindrical members, a guard rail rectangular in :cross section, plunger rods secured 'to one face ofthe guard rail and' extending at right angles therefrom, said plunger of the cylindrical membersand tothe plunrods slidably arranged in the cylindrical members and bearing against the fiire eents each, by addressing the Commissioner of Tatents, Washington, D; G.
